Troubleshooting
Action
7. To vent the chamber vacuum,
grasp the red rubber hose and
pull it up until it comes off
of the pump fitting (see
Figure 4-3). Use a back-and-
forth motion as you pull; this
takes quite a bit of force.
8. Replace the hose by pushing
it down over the fitting as far
as it can go.
9. Pull the interlock lever out
and to the left, and while
holding it out, step on the
foot pedal.
10.Remove your sample.

Result
The vacuum will be completely vented several seconds after the hose
is detached.
➠
NOTE
Several tubing lines are tied to the red hose. As
you grasp the hose, place your hand over these
lines. Make sure that they stay connected as
you pull.
!
CAUTION
Do not twist the hose to the left (counterclock-
wise) as you pull the hose, or you will unscrew
the hose fitting.
!
WARNING
Never try to slow or stop the rotor by hand.
